摘要

"Instrument to perform therapy on a tooth and method of manufacturing an instrument for use in performing endodu00c8ntico therapy of root canal of a tooth.An instrument for use in performing endodu00f3ntico therapy of root canal of a tooth having at least a straight groove that prevents self screwing in or self screwing of the instrument in the intErior in a root canal during use.The instrument includes a shaft having a central longitudinal geometrical axis, a part of the shaft and an active part is elongated extending from the shaft along the axis geometric central.The active part is elongated having a proximal end, a distal end, and at least a portion of the peripheral surface of the active part.The straight groove forming at least one cutting edge on the peripheral surface.The straight groove may be formed of a plurality of sections of a groove arranged on the peripheral surface of the instrument.The plurality of sections of each groove angularmente displaced around the axis geometric central between them. A method of manufacturing a tool endodu00f3ntico is also presented.
